Vitamin D (25-Hydroxy) Testing
How to check your Vitamin D levels with a home finger-prick blood test kit
What Is A Vitamin D Test For?
A Vitamin D test is also known as an Ergocalciferol (Vitamin D2), Cholecalciferol (Vitamin D3), Calcidiol or Calcitriol test.
Vitamin D is an essential vitamin, mostly produced in the skin by sunlight (up to 90%) although it is also absorbed from food & supplements.
Its main role is regulating how the body absorbs calcium, phosphate and magnesium from the gut.
Correct levels of these minerals are vital for healthy bone growth.

What If Vitamin D Test Levels Are High?
High levels of vitamin D typically result from excessive supplementation rather than natural exposure.
Together with high levels of calcium this can lead to damage to blood vessels, kidneys and other organs.
What If Vitamin D Test Levels Are Low?
Although typically due to a lack of sunlight, note that low Vitamin D levels can also be caused by underlying conditions that reduce the absorption of Vitamin D from food.
Parathyroid hormone levels, kidney function, taking certain medications or being at a higher risk from fractures should also be considered when seeking treatment.
Consultation with a medical professional is recommended to fully understand the cause of deficiency and to ensure appropriate treatment.
NICE recommend treating vitamin D deficiency with fixed high doses of a vitamin D supplement for 6 - 10 weeks followed by lifelong maintenance treatment. You can learn more here.
